Add Level Information to debug save name

Hi,

while the debug log creation works now, I don't have a bloody clue which is which at this point. Knowing in which level (or the menu) one was being made in the filename would make this a lot easier.

Probably irrelevant to most people as they only write one or two tickets/bugreports.

I don't think it needs to write out the day's name in full, so there's ample space in the filename. Having the day's name in there also messes up the sorting order...
